ITEM EXPLANATION: The Romeria Drainage Improvement Project is the replacement of an existing concrete lined drainage channel which runs through open space westerly of Romeria Street. Channel improvements include removal of the existing damaged concrete channel. The concrete channel will be replaced in the same location. Slope protection at the headwall connecting the channel to the storm drain system and an all-weather maintenance access road are included in the channel improvements. The La Costa Avenue Slope Repair Project includes repairing an area subject to historic landslides located on city property south of La Costa Avenue just westerly of the channel. Installation of a subdrain system and geotextile fabric within the reconstructed slope will prevent future slope movement. The area outside the channel footprint impacted as a result of the construction of the projects will be replanted under a separate contract. The remaining impacts from both projects will be mitigated at the Lake Calavera Preserve under a separate contract. An Engineer's Estimate of the construction cost for the Romeria Drainage Improvement and La Costa Avenue Slope Repair Projects was prepared by Rick Engineering Company, the consulting engineer of work and totals $405,000.
